Gaussberg is a nunatak composed of lamproite pillow lava situated on the coast of East Antarctica. It is the most isolated Quaternary volcanic centre in Antarctica but it is important palaeoenvironmentally and petrologically out of all proportion to

The principal deep crustal rock types found at the La Olivina xenolith locality in southeastern Chihuahua, Mexico, are mafic granulites, paragneisses, and intermediate- to silicic-composition orthogneisses. These granulite facies xenoliths are interp

The use of metamorphosed basic dykes as one of the most important single field criteria for subdividing gneisses in high grade areas into different chronological units is defended. The universal applicability of the “lower greenstone-granite-upper

Three different zircon size fractions, prepared from a single sample of Uivak II gneiss, yielded highly discordant lead–uranium isotopic ratios. The data define a discordia chord which intersects concordia at 3760 ± 150 Ma and about 2500 Ma. The u

Lithological and earlier isotopic studies suggest that several of the older rock units in the Archean gneiss complex of north Labrador can be correlated with those of the Godthaabsfjord area of west Greenland (West Greenland Correlation = WGC). Howev

It is proposed that some of the surface features of Europa may be due to processes occurring within a planet in which hydrated silicates are stable. Based on considerations of the mechanical properties of hydrated silicates and ice and the likely thi

SummaryIn high-grade regionally metamorphosed tectonites three varieties of micro- structures are recognized, namely (1) granoblastic, (2) granoblastic elongate, (3) anastomosing. Relative and absolute grain size, combined with grain boundary shape,

A path of geophysical development which takes into account the petrological sequence is presented to describe the thermal evolution of Europa. On the basis of considerations of the likely temperature-pressure conditions in the Europa zone of the circ
